Sexually transmissible infections (STIs) are infections that are transmitted during sex through body contact or the exchange of body fluids (i.e. blood, mucus or saliva). Sexual contact includes vaginal or anal intercourse or touching, fingering or sucking/kissing/licking a penis, vagina or anus.

STIs can be caused by viruses (e.g. HIV, herpes, genital warts), bacteria (e.g. chlamydia, gonorrhoea), or parasites (e.g. crabs, scabies).

If you manage your sexual health and play it safe you can significantly reduce your risk of getting an STI, or passing it on to a sexual partner.

Infection rates for some STIs – such as HIV, gonorrhoea and syphilis – are much higher among gay men than in the general population.

The best way to prevent HIV transmission among men is to have safe sex by using a condom and water based lubricant for anal sex.

Using condoms can also help prevent the transmission of some other STIs, but not all STIs.
